Hi, I'm Kyle Hoagland, professor of aquatic ecology/limnology in the School of Natural Resources.

I'm associated with the environmental studies, fisheries and wildlife and water science majors, the aquatic ecology and hydrologic sciences graduate specializations and the water science program area. In the past, I also directed UNL's Water Center (2000-2009), a national network of water resources research institutes, and I served as interim director of the School of Natural Resources (2001-2003).

My research laboratory has focused on the toxicity of agricultural chemicals to algae in lakes and streams, with an emphasis on the two most commonly used herbicides, atrazine and alachlor. This research has been conducted from the population to the community levels, at both chronic (more diffuse, long-term) and acute (more intensive, short-term) exposures. In addition, the lab has addressed other aquatic ecology issues, including lake restoration, lake classification and water quality assessment. Most recently, my lab has focused on the effects of cyanobacterial neurotoxins, particularly BMAA, on humans and on fish populations.

Since coming to UNL in 1990, I've been involved in programs that address such concrete problems as agricultural chemicals, herbicides, insecticides and nutrients that commonly occur in streams, wetlands, lakes, and ponds in Nebraska and throughout the agricultural Midwest. These pollutants affect water quality at the population, community, and ecosystem levels, sometimes in profound ways. Understanding their dynamics and impacts at various levels of ecological organization and how land-use and -management might be improved to limit their effects is key to managing this precious natural resource.

I have a bachelor's in zoology from Michigan State University (1973), a master's in aquatic biology from Eastern Michigan University (1975) and a doctorate in life sciences (phycology) from the University of Nebraska-Lincoln (1981). I was gone from UNL for nearly ten years, first as a postdoc at the University of Maine and then at Louisiana State University, then as a faculty member at Texas Christian University for seven years, before returning to UNL in the summer of 1990.

During my tenure at UNL, I have taught Limnology both on campus and at Cedar Point Biological Station (as well as Aquatic Botany at CPBS) and on campus courses in Advanced Limnology and Wetlands (both were team taught courses).
